The Sigma 30mm F2.8 DN is designed exclusively for mirrorless interchangeable lens cameras and offers the equivalent angle of view as a 60mm lens (35mm equivalent focal length) on the Micro Four Thirds systems and 45mm (35mm equivalent focal length) on the E-mount system. This lens benefits from a newly developed linear AF motor, which moves the lens elements directly without the need for gears or the drive of other mechanical parts. This system ensures accurate and quiet autofocusing, making the lens suitable for video recording as well as still photos. The lens is available in either a silver or black finish.
